One path to a more realistic view of limited precision is to explore microscopic models for the interactions between TF proteins and their binding targets along the genome, and for the mechanisms by which binding events influence transcription [1]}, [2]}, [3]}, [4]}, [5]}, [6]}. But then our conclusions depend on our choice of model, and almost certainly our model will be wrong in detail. Instead we can try to abstract away from concrete models, hoping to capture the essence of limited precision in a more general way.
